[thelist] contract vs. requirements doc

[Bob Meetin]

I'm reviewing a contract this AM.  As a technician, web technologist, I 
work best when I have a reasonably defined list of functional 
requirements in front of me.  With this client we've reviewed the 
functional requirements several times and agreed upon deliverables.

What is an acceptable way in this industry to refer to the requirements 
but not include them in a contract?  Or is it really up to the parties 
involved?  Including these details makes for a lengthy document.
